PROBLEM TO BE SOLVED: To provide a nonwoven fabric hardly wrinkled even if getting deformation, and an absorbent article using the same.SOLUTION: The nonwoven fabric is mainly composed of a conjugated fiber including a first constituent and a second constituent, which are fiber forming constituents, where the first constituent and the second constituent are thermoplastic resins respectively as principal constituents, the first constituent includes a long chain branch structure polyolefin resin. The nonwoven fabric regarding shear forces measured by tensile/share measuring instrument satisfies the following relation: 1≤DO/Dmax≤5, where DO is a rate of change of a shear force per angle around the shear angle 0 degree, and Dmax is a rate of change of a shear force per angle having a shear angle obtainable of a maximum shear force as a maximum angle.SELECTED DRAWING: Figure 3【課題】変形を受けてもシワが入りにくい不織布およびそれを用いた吸収性物品の提供。【解決手段】繊維形成成分である第１の成分と第２の成分とを含む複合繊維を主体とする不織布であって、前記第１の成分および前記第２の成分はそれぞれ熱可塑性樹脂を主成分とし、前記第１の成分は長鎖分岐構造ポリオレフィン樹脂を含み、前記不織布は、引張・剪断測定装置による剪断力の測定において剪断角０度を中心とする角度あたりの剪断力の変化率をＤOとし最大剪断力が得られる剪断角を最大角度とする角度あたりの剪断力の変化率をＤｍａｘとしたときに、１≦ＤO／Ｄｍａｘ≦５の関係を満たす、不織布。【選択図】図３
